Re: Try pdfcrop before printing PDF files |
Thanks for your additions, martyveldman and ecossais.
There are many scanned books with pages having text to the left and right alternatively. Here pdfcrop is very useful as it estimates the minimum area for each page separately, and yet outputs the whole thing in one pdf file.
There is this though: pdfcrop 1.20 apparently takes only standard paper sizes. In the Internet Archive books, I have to first change the paper size to A4 (via "Print as PDF" feature of PDF readers).
---
Update [2012-12-28]: It has nothing to do with paper-sizes. Something else is wrong, which causes failure of
pdftex (which pdfcrop uses for page inclusion) with the error: `PDF inclusion: invalid font in reference type <dictionary>'. (This happens for many, but not all IA pdf files.) For the cause of this failure, and solution, please search for another post by me.
An incomplete post is here:

The second
pdfcrop above (Eric Doviak’s) should not have problem with IA files. I have not tried Doviak’s pdfcrop, but the files
pdfedit produces are like the IA files (i.e., pdfedit files have exactly the same issue as the IA files), so pdfedit should have no problem with processing IA files.

Re: Try pdfcrop before printing PDF files |
Thanks very much, I must have a look at those.
My personal favourite is 'briss'. An extremely simple program that allows one to graphically, manually chop off margins. I use it to crop PDFs before putting them on an ebook reader :) It works on Windows and Linux. I think there are screenshots

Also check unpaper |
http://unpaper.berlios.de/unpaper is a post-processing tool for scanned sheets of paper, especially for book pages that have been scanned from previously created photocopies. The main purpose is to make scanned book pages better readable on screen after conversion to PDF. Additionally, unpaper might be useful to enhance the quality of scanned pages before performing optical character recognition (OCR). unpaper tries to clean scanned images by removing dark edges that appeared through scanning or copying on areas outside the actual page content (e.g. dark areas between the left-hand-side and the right-hand-side of a double-sided book-page scan). The program also tries to detect disaligned centering and rotation of pages and will automatically straighten each page by rotating it to the correct angle. … It is always a good idea to manually control the results of unpaper and adjust the parameter settings according to the requirements of the input. Each processing step can also be disabled individually for each sheet. Input and output files can be in either .pbm , .pgm or .ppm format … Conversion to PDF can e.g. be achieved with the Linux tools pgm2tiff, tiffcp and tiff2pdf.
